Colonoscopy is useful in radiation therapy–induced gastrointestinal bleeding and in the treatment of colonic polyp lesions. Endoscopic treatment of radiation-induced bleeding includes topical application of formalin, Nd:YAG (neodymium-doped yttrium aluminium garnet) laser therapy, and argon plasma coagulation. Neoplastic bleeding due to polyps requires polypectomy. Patients diagnosed with colonic tumors may require surgical resection.
